Application filed December 12, 1912.

To all whom it may concern:

Be it known that I, DWIGHT K. HALL, a citizen of the United States, and a resident of the town of Goshen, county of Orange, and State of New York, have invented certain new and useful Improvements in Bedstead Construction, of which the following is a specification.

My invention relates to an improvement in the construction of metallic bedsteads, particularly those made of brass tubing, the sections of which are set together with interlocking joints in the manner described in my prior Patent, #1028706, dated June 4th, 1912.

The object of the present invention is to effect a more secure interlocking engagement between the parts without, however, letting any fastening devices appear on the exterior of the bed, and at the same time without such degree of complication in the structure of the bed as would render the practical employment of the invention a hindrance to commercial conditions of the manufacture and sale of such articles. I accomplish this end by furnishing the parts with an interlocking engagement and securing within one of the tube sections a spring lock which coacts with the parts and holds them firmly in locked arrangement, said device, however, in no way interfering with the ease with which the tube sections may be engaged together, after the principle of operation described in the prior patent aforesaid.

Reference is now had to the accompanying drawings for a detailed description of the invention, and in these drawings Figure 1 shows an elevational view of one of the end members of the bed with parts broken away to illustrate the invention; and Fig. 2 shows a detail perspective of two of the tube sections, one also being shown broken away to illustrate the interior.

The improved joint to which my invention relates is applicable to various situations on the bed. Thus, it may be between the horizontal railings a and the posts 6, referring to Fig. 1, or between the vertical tubes 0 and the railing at. The said device is of substantially the same-construction, irrespective of its location.

Referring particularly to Fig. 2, let a represent the top horizontal rail or tube shown in Fig. 1, and 0 one of the vertical tubes,

also shown in said view. The rail a is formed with an opening 03, therein, which is of a form corresponding to the cross-sectional form of the tube 0 and the tube 0 has its end arranged to enter this opening (Z, said end being beveled or inclined as indicated at e. The parts are fitted together by introducing the beveled end of the tube 0 into the opening d and engaging a notch f in the side of the tube with one of the side walls of the opening (6, in the manner shown. The engagement of the parts is completed by a swinging or turning movement of the tube a with respect to the tube a (again referring to Fig. 2), after which the said tube 0 is disposed in true perpendicular to the tube a and the whole of the inclined end 6 is received within said tube.

The spring lock 9 is located within the tube 0 and is in the form of a U-shaped leaf spring, one end of which is soldered or otherwise secured to the inner side of the tube 0 opposite the notch 7, and the other or free end of which extends over the notch within the tube. When the tubes are engaged in the manner described, said free end of the spring lock 9 will engage the edge or wall of the opening (Z in the tube a which edge or wall is received within the slot 7" of the tube 0, and the spring lock will then press the beveled side of the tube 0 toward the adjacent wall of the opening a? in the tube a, holding the parts square and firm. The play of the tube 0 within the opening (3 is not sufficient to allow the walls of the slotf at any time to clear their engagement with the tube a, but there is a slight play allowed which is sufficient to permit the above described operation of the spring lock 9.

Having thus described my invention, what I claim is:

1. A bedstead constructed of metallic tubing comprising engaging tubular sections, one of which is furnished with an opening to receive the end of the other, and a spring lock situated within the second tube in position to press the two tubes against each other when they are engaged and furnish a lock for the purpose specified.

2. A bedstead construct-ion of metallic tubing comprising engaging tubular sections, one section being furnished with an opening to receive the end of the remaining section, the remaining section having a slot at one side thereof adapted to engage the edge of said opening when the sections are unlocked, and a spring lock situated within the second section and extending across said slot whereby to press the two tubes against each other when they are engaged and furnish a lock for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses this 8 day of Oct.
